Abstract: ABSTRACT         The present invention teaches an oriented olefinic film, e.g. polyethylene, which can be made with highly oriented crystalline phase unit cells.  The film of the present invention has crystalline phase unit cells with an a-axis highly oriented in the machine direction and consequently, improved physical properties.  Specifically, the film has a good cutter bar tear, a high degree of puncture resistance and limited tear propagation in the transverse direction. The film is made by controlling the heat transfer of a chill roll to the olefinic extrudate.  Heat transfer is accomplished by pinning the olefinic film with an air knife as it is extruded on the chill roll.  The pin is controlled by adjusting the temperature of the chill roll and the focus velocity of the air knife. 34,708-F

Abstract: ABSTRACT OF THE DISCLOSURE A system     for indicating the level of material in a vessel      as a function of material capacitance comprising a resonant circuit      including a capacitance probe      adapted to be disposed in a vessel so as to be responsive to variations in capacitance as a function of material level.  An oscillator      has an output coupled to the resonant circuit and to a phase detector      for detecting variations in phase angle as a function of probe capacitance. Level detection circuitry         is responsive to an output of the phase detector and to a reference signal indicative of a level of material for indicating material level as a function of a difference between capacitance at the probe and the reference signal.   In  the preferred embodiments  of  the  invention  disclosed,  an  automatic calibration   circuit           adjusts   the   resonance characteristics  of  the  parallel  resonant  circuit  in  a predetermined or preprogrammed manner during a calibration operation to a point indicative of the predetermined reference material level.  A timer      measures the duration of the automatic calibration operation for indicating conditions at the probe, such as the amount of material coated onto the probe.   A reed switch      is positioned adjacent to the cover of a housing which encloses the electronics and is responsive to variations in magnetic flux from externally of the housing for indicating a calibration operation without removing the housing cover.

Abstract: The invention relates to a process and a preservative for the preservation of animal feed. According to the process, acid-containing substance is added to fresh, newly harvested fodder in an amount sufficient to increase the acidity of the fodder immediately to below 4.5 at the most, preferably to below 4 in accordance with the principle of the AIV System. Spent liquor from acid pulping, optionally concentrated to desired concentration, is used as acid-containing substance. According to the invention, the liquor used consists of the spent liquor from a pulping process, wherein formic acid and/or a mixture of formic acid and hydrogen peroxide has been used for defibering the cellulosic raw material. Such a solution contains before concentration about 30 to 50 weight per cent lignin, about 5 to 20 weight per cent poly-saccharides, about 10 to 20 weight per cent mono- and oligo-saccharides and about 30 to 50 weight per cent monosacchari-des and lignin fragments calculated on basis of the dry matter. The pH of the ensilage feed can easily be adjusted to its most preferable value (3.5 to 4.0), while securing a sufficient amount of sugars and, thus, accurate fermentation by means of the sugars in the spent liquors.

The interconnection is such that depending upon the pedal activated a different tone or digital signal will be generated.  The user can readily reconnect the interface to vary the signal to pedal correspondence for changes in Voice Mail Systems or to implement other Voice Mail System commands.  The DTMF tone generator is connected in series between the hand set and base set of a telephone so that system can be readily connected to an existing telephone and so that the tones can be sent over the phone line to a Voice Mail System.

Abstract: The printed products to be wound up are delivered by one belt conveyor of a conveying arrangement. The latter comprises two belt conveyors which conjointly form a conveying channel with a defined inlet and outlet. Conveyor belts of both of these two belt conveyors are guided such that the conveying channel has a curved path directed toward a rotatable winding mandrel. The conveying arrangement is pivotable about an axis of rotation of a drive drum of the innermost conveyor belt of the two conveyor belts and is pressed against the winding mandrel, respectively against the product coil or wound package forming on the winding mandrel, by a winding strap capable of being placed under tension and which is withdrawn from a winding strap supply roll and runs through a portion of the conveying channel and is connected with the winding mandrel. A separate contact or pressing mechanism can be forgone. The design of the conveying arrangement permits a compact construction and free choice of the delivery location of the printed products to the winding mandrel.
